<PRE><B>Question 9352</B>
Let X = dimes

Let Y = Nickels

We know Y = 3X

We also know that .10 = Dimes and .05 = Nickles

So X+Y=1.50

We substitue the following:

.10X + 3(.05X)=1.50

.10X + .15X = 1.50

.25X = 1.50

Divide both sides by .25

X = 6 Dimes

So we know we have 3 times as many nickels as dimes, 6 x 3 = 18.

Answer:

6 dimes = .60
18 Nickels = .90

Total = 1.50</PRE>
